A boy and his... hog

An image search led to the French National Library ("Tame animals of Mr Wingfield Ampthill child beside a saddled pig"), via Europeana.  There is a photo of the boy on the hog here.

But the location seems to be England, because there's a Pathe video of grown men riding llamas and ostriches (and this hog) at the Ampthill Zoo in the East Anglia Film Archive.
